Dog boarding near Dulles

I'll be boarding my dog for 7 nights & plan for him to stay in the Sterling area (near Dulles airport). Looking at Healthy Hound Playground or Olde Town Pet Resort Sterling. Wondering if any dog owners have experience with these places and could recommend one or the other?

He's great in a doggy daycare environment - gets along with other dogs & loves to play. I'd prefer for him to be able to play with other dogs most of the day rather than being cooped up in a kennel.

TIA!
